already a widely used feedstock, supporting the production of a range of materials, including plastics and synthetic fuels. Its continued use in these applications provides a pathway to reduce emissions without requiring fundamental changes to downstream processes. Methanol also has a role as a hydrogen carrier, enabling hydrogen to be stored and transported in liquid form. This can support energy storage and distribution in systems where direct hydrogen infrastructure is limited. The existence of established global supply chains further enhances methanol’s deployment potential. Infrastructure for storage, transport, and distribution is already in place, allowing renewable methanol to be integrated into existing markets with relatively low additional investment. Alongside this infrastructure readiness, policy frameworks and market signals are playing an increasingly important role in accelerating the deployment of sustainable methanol. In the maritime sector, regulatory pressure is intensifying, with targets set to reduce emissions intensity and move towards net-zero operations over the coming decades. These measures are driving demand for alternative fuels that can be deployed within existing vessel designs and fuel supply systems. In parallel, regional policies are supporting the development of low-carbon fuels. In Europe, initiatives such as renewable fuel mandates and sector-specific regulations for shipping and aviation are creating incentives for the adoption of fuels derived from non-fossil sources. Similar trends are emerging in other regions, where carbon pricing mechanisms and industrial decarbonisation strategies are increasing the attractiveness of sustainable fuel pathways. This policy momentum is beginning to translate into commercial activity. Shipping operators are placing orders for methanol-capable vessels, while project developers are advancing large- scale production facilities based on both biomass and CO₂-derived pathways. The scale of these projects, in some cases reaching hundreds of thousands of tonnes per year, reflects growing confidence in methanol as a viable option for reducing emissions across multiple sectors. At the same time, challenges remain. The cost gap between renewable methanol and

conventional fuels persists, particularly in e-methanol production where hydrogen costs remain high. In addition, the development of consistent certification frameworks and clear lifecycle accounting methodologies is still evolving. Addressing these issues will be essential to support investment and enable broader market adoption. Despite these constraints, the combination of regulatory drivers, increasing demand, and advancing project development indicates that sustainable methanol is moving beyond early- stage deployment. It is increasingly being positioned within policy and industry strategies as a practical route to reduce emissions in sectors where alternatives remain limited. Engineering continuity and the role of proven design in scaling One of the key challenges in deploying sustainable fuels is moving from pilot-scale projects to large-scale commercial operation. This transition requires not only technical feasibility but also confidence in long-term performance and economic viability. Methanol production benefits from a strong foundation of proven design. Large-scale methanol plants based on fossil feedstocks have been operating for decades, establishing reliable approaches to reactor design, synthesis loop configuration, and heat integration. These principles are directly applicable to sustainable methanol production. Modern low-carbon methanol plants build on this experience by adapting established process configurations to new feedstocks. This includes the use of synthesis loops with gas recycling to overcome equilibrium limitations, as well as reactor designs that enable effective temperature control and heat management. The methanol synthesis reaction is exothermic, requiring efficient heat removal to maintain stable operation and protect catalyst performance. Reactor designs developed for conventional plants are used to manage these conditions, allowing for reliable operation under a range of feed compositions. Catalyst performance is particularly important in CO₂-based processes, where the reaction produces significant amounts of water. This creates hydrothermal conditions that can affect
